<A NAME="X-REF352146494"></A><h1>Defining a graph's properties </h1>
<A NAME="TI7879"></A><p>This section describes properties of a graph that are used
regardless of whether the graph is in a DataWindow object or in a window. To define the properties of
a graph, you use the graph's Properties view. For general
information about the property pages, see <A HREF="pbugp226.htm#X-REF352150508">"Using the graph's
Properties view"</A>.</p>
<A NAME="X-REF356369840"></A><h2>Using the General page in the graph's Properties view</h2>
<A NAME="TI7880"></A><p>You name a graph and define its basic properties on the General page in
the graph's Properties view.</p>
<A NAME="TI7881"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify the basic properties of a graph:</p>
<ol><li class=fi><p>Select Properties from the graph's
pop-up menu and then select the General page in the Properties view.</p></li></ol>
<br><A NAME="TI7882"></A><h4>About the model graph in the Design view</h4>
<A NAME="TI7883"></A><p>As you modify a graph's properties, PowerBuilder updates
the model graph shown in the Design view so that you can get an
idea of the graph's basic layout:<A NAME="TI7884"></A>
<ul>
<li class=fi>PowerBuilder uses the graph title and axis labels
you specify.</li>
<li class=ds>PowerBuilder uses sample data (not data from your DataWindow object) to
illustrate series, categories, and values.
</li>
</ul>
</p>
<A NAME="TI7885"></A><p>In Preview view, PowerBuilder displays the graph with data.</p>
<A NAME="TI7886"></A><h4>Naming a graph</h4>
<A NAME="TI7887"></A><p>You can modify graphs at runtime. To reference a graph in
code, you use its name. By default, the graph is named gr_<i>n</i>.</p>
<A NAME="TI7888"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To name a graph:</p>
<ol><li class=fi><p>On the General properties page for the
graph, assign a meaningful name to the graph in the Name box.</p></li></ol>
<br><A NAME="TI7889"></A><h4>Defining a graph's title</h4>
<A NAME="TI7890"></A><p>The title displays at the top of the graph.</p>
<A NAME="TI7891"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify a graph's title:</p>
<ol><li class=fi><p>On the General properties page for the
graph, enter a title in the Title box.</p></li></ol>
<br><p><img src="images/note.gif" width=17 height=17 border=0 align="bottom" alt="Note"> <span class=shaded>Multiline titles</span> <A NAME="TI7892"></A>You can force a new line in a title by embedding ~n.</p>
<A NAME="TI7893"></A><p>For information about specifying properties
for the title text, see <A HREF="pbugp228.htm#BFCBCIED">"Specifying text properties
for titles, labels, axes, and legends"</A>.</p>
<A NAME="TI7894"></A><h4>Specifying the type of graph</h4>
<A NAME="TI7895"></A><p>You can change the graph type at any time in the
development environment (To change the type at runtime, modify a
graph's GraphType property.)</p>
<A NAME="TI7896"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify the graph type:</p>
<ol><li class=fi><p>On the General properties page for the
graph, select a graph type from the Graph Type drop-down list.</p></li></ol>
<br><A NAME="TI7897"></A><h4>Using legends</h4>
<A NAME="TI7898"></A><p>A legend provides a key to your graph's series.</p>
<A NAME="TI7899"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To include a legend for a series in a graph:</p>
<ol><li class=fi><p>On the General properties page for the
graph, specify where you want the legend to appear by selecting
a value in the Legend drop-down list.</p></li></ol>
<br><A NAME="TI7900"></A><p>For information on specifying text properties
for the legend, see <A HREF="pbugp228.htm#BFCBCIED">"Specifying text properties
for titles, labels, axes, and legends"</A>.</p>
<A NAME="TI7901"></A><h4>Specifying point of view in 3D graphs</h4>
<A NAME="TI7902"></A><p>If you are defining a 3D graph, you can specify the point
of view that PowerBuilder uses when displaying the graph.</p>
<A NAME="TI7903"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify a 3D graph's point of view:</p>
<ol><li class=fi><p>On the General properties page for the
graph, adjust the point of view along the three dimensions of the
graph:<A NAME="TI7904"></A>
<ul>
<li class=fi>To change the perspective, move
the Perspective slider.</li>
<li class=ds>To rotate the graph, move the Rotation slider.</li>
<li class=ds>To change the elevation, move the Elevation slider.
</li>
</ul>

                        </p></li>
<li class=ds><p>Define the depth of the graph (the percent the
depth is of the width of the graph) by using the Depth slider.</p></li></ol>
<br><A NAME="TI7905"></A><h2>Sorting data for series and categories</h2>
<A NAME="TI7906"></A><p>You can specify how to sort the data for series and categories.
By default, the data is sorted in ascending order.</p>
<A NAME="TI7907"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify how to sort the data for series and
categories in a graph:</p>
<ol><li class=fi><p>Select Properties from the graph's
pop-up menu and then select the Axis </p><p>page in the Properties view.</p></li>
<li class=ds><p>Select the axis for which you want to specify
sorting.</p></li>
<li class=ds><p>Scroll to Sort, the last option on the Axis page, and
select Ascending, Descending, or Unsorted.</p></li></ol>
<br><A NAME="BFCBCIED"></A><h2>Specifying text properties for titles, labels, axes, and legends</h2>
<A NAME="TI7908"></A><p>A graph can have four text elements:<A NAME="TI7909"></A>
<ul>
<li class=fi>Title</li>
<li class=ds>Labels for the axes</li>
<li class=ds>Text that shows the values along the axes</li>
<li class=ds>Legend
</li>
</ul>
</p>
<A NAME="TI7910"></A><p></p>
<br><img src="images/graph38.gif">
<A NAME="TI7911"></A><p>You can specify properties for each text element.</p>
<A NAME="TI7912"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify text properties for the title, labels,
axis values, and legend of a graph:</p>
<ol><li class=fi><p>Select Properties from the graph's
pop-up menu and then select the Text page in the Properties view.</p></li>
<li class=ds><p>Select a text element from the list in the Text Object
drop-down list.</p><br><img src="images/graph40.gif"><br>
</li>
<li class=ds><p>Specify the font and its characteristics.</p></li></ol>
<br><A NAME="TI7913"></A><h4>Using Auto Size</h4>
<A NAME="TI7914"></A><p>With Auto Size in effect, PowerBuilder resizes the text appropriately
whenever the graph is resized. With Auto Size disabled, you specify
the font size of a text element explicitly.</p>
<A NAME="TI7915"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To have PowerBuilder automatically size a text element
in a graph:</p>
<ol><li class=fi><p>On the Text properties page for the graph,
select a text element from the list in the Text Object drop-down
list.</p></li>
<li class=ds><p>Select the Autosize check box (this is the default).</p></li></ol>
<br><A NAME="TI7916"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify a font size for a text element in a
graph:</p>

<li class=ds><p>Clear the Autosize check box.</p></li>
<li class=ds><p>Select the Font size in the Size drop-down list.</p></li></ol>
<br><A NAME="TI7917"></A><h4>Rotating text</h4>
<A NAME="TI7918"></A><p>For all the text elements, you can specify the number of degrees
by which you want to rotate the text.</p>
<A NAME="TI7919"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify rotation for a text element in a graph:</p>
<ol><li class=fi><p>On the Text properties page
for the graph, select a text element from the list in the Text Object
drop-down list.</p></li>
<li class=ds><p>Specify the rotation you want in the Escapement box using
tenths of a degree (450 means 45 degrees).</p></li></ol>
<br><A NAME="TI7920"></A><p>Changes you make here are shown in the model graph in the
Design view and in the Preview view.</p>
<A NAME="TI7921"></A><h4>Using display formats</h4>
<A NAME="TI7922"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To use a display format for a text element in
a graph:</p>
<ol><li class=fi><p>On the Text properties page for the graph,
select a text element from the list in the Text Object drop-down
list.</p></li>
<li class=ds><p>Type a display format in the Format box or choose
one from the pop-up menu. To display the pop-up menu, click the
button to the right of the Format box.</p></li></ol>
<br><A NAME="TI7923"></A><h4>Modifying display expressions</h4>
<A NAME="TI7924"></A><p>You can specify an expression for the text that is used for
each graph element. The expression is evaluated at execution time.</p>
<A NAME="TI7925"></A><p><img src="images/proc.gif" width=17 height=17 border=0 align="bottom" alt="Steps"> To specify an expression for a text element in
a graph:</p>
<ol><li class=fi><p>On the Text properties page for the graph,
select a text element from the list in the Text Object drop-down
list.</p></li>
<li class=ds><p>Click the button next to the Display Expression box.</p><p>The Modify Expression dialog box displays.</p></li>
<li class=ds><p>Specify the expression. </p><p>You can paste functions, column names, and operators. Included
with column names in the Columns box are statistics about the columns,
such as counts and sums.</p></li>
<li class=ds><p>Click OK to return to the graph's Properties view.</p></li></ol>
<br><A NAME="TI7926"></A><h4>Example</h4>
<A NAME="TI7927"></A><p>By default, when you generate a pie graph, PowerBuilder puts
the title at the top and labels each slice of the pie with the percentage
each slice represents of the whole. Percentages are accurate to
two decimal places.</p>
<A NAME="TI7928"></A><p>The following graph has been enhanced as follows:<A NAME="TI7929"></A>
<ul>
<li class=fi>The current date displays
in the title</li>
<li class=ds>The percentages are rounded to integers</li>
<li class=ds>The raw data for each slice is shown in addition
to the percentages
</li>
</ul>
</p>
<br><img src="images/graph46.gif">
<A NAME="TI7930"></A><p>To accomplish this, the display expressions were modified
for the title and pie graph labels:</p>
